<h2>Customising grid Editing</h2>
<h3>Description</h3>
<p>
This generic hook function is called whenever a grid grob is edited
via <code>grid.edit</code> or <code>editGrob</code>.
This provides an opportunity for customising the editing of a
new class derived from grob (or gTree).
</p>
<h3>Usage</h3>
<pre>
editDetails(x, specs)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
A grid grob. </td></tr>
<tr valign="top"><td><code>specs</code></td>
<td>
A list of named elements. The names indicate the
grob slots to modify and the values are the new values for the slots. </td></tr>
</table>
<h3>Details</h3>
<p>
This function is called by <code>grid.edit</code> and <code>editGrob</code>.
A method should be written for classes derived from grob or gTree
if a change in a slot has an effect on other slots in the grob or
children of a gTree (e.g., see <code>grid:::editDetails.xaxis</code>).
</p>
<p>
Note that the slot already has the new value.
</p>
<h3>Value</h3>
<p>
The function MUST return the modified grob.</p>
